Went to see the water last year, but didn't fish it as they had a corporate day. At the time looked good, 3 lakes, top going down levels with fresh water feed. Lovely clear water and very shallow at margins with plenty of weed growth.
Advice I had at the time was floating line and imitative patterns depending on time of year, use any features available, bottom lake has a couple of duck platforms and central island where they mill about. The couple of anglers I spoke to said when it fished well was great with good quality fish, but when nothing doing can be dire.
Sorry

not very helpful, but please post and let me know how you get on and if the prices have increased, fancy trying it out myself sometime this season.
